@ mark - Yes and no I would think. Some armies will have a terrible time removing that many 3+ armour saves. Then again any list with a couple of helldrakes is going to crispy them no problem since there isn't any dedicated anti-air. Also Predators are not that durable and they are the only reliable anti-tank in the list. A seriously nasty deathstar unit might give this army a fit until Kharn can get there.
